Enzyme Triggered Redox Altering Chemical Elimination (E-Trace) Immunoassay - The present invention is directed to electronic methods of detecting target analytes such that upon binding of the target analyte a shift in electrochemical potential is seen. This assay relies on the use of an electroactive moiety (“EAM”) that is attached to an electrode and comprises a self-immolative moiety, whose presence gives the EAM a first E0, and whose absence, upon irreversible cleavage gives the EAM a second E0. This difference is detected, and if such change occurs, it is an indication of the presence of a target analyte.

ENZYME CASCADE METHODS FOR E-TRACE ASSAY SIGNAL AMPLIFICATION - The disclosure also relates to novel methods for detection of biological targets using amplification steps in conjunction with conversion of functional groups attached to a transitional metal complex, resulting in quantifiable electrochemical signal at two unique potentials, E°

PSA ENZYMATIC ACTIVITY: A NEW BIOMARKER FOR ASSESSING PROSTATE CANCER AGGRESSIVENESS - The disclosure provides for methods to determine prognosis, aggressiveness, and progression of prostate cancer with the ability to differentiate between aggressive and non-aggressive prostate cancer. The method utilizes the differential enzymatic activity in patient samples, for example of enzymatically active prostate specific antigen (PSA) activity, in order to determine the aggressiveness and prognosis of prostate cancer, and monitor the progression of prostate cancer therapy. The invention also encompasses assay platforms (e.g., optical or electrochemical) that specifically detect PSA-triggered peptide cleavage events.

Methods of Making Functionalized Internal Olefins and Uses Thereof - A method of isomerizing a substance includes combining a substance including a terminal alkenyl group and a substance including a fluorosulfonic acid group in a reaction mixture, and forming a substance including a 2-alkenyl group from the substance including a terminal alkenyl group in the reaction mixture. The method may be used to functionalize a substance, as the substance including a 2-alkenyl group can be reacted with a functionalizing agent to form a substance including a first functional group. The methods may be used to form a dicarboxylic acid, such as suberic acid, from a renewable feedstock.
